To get to King's College bar just travel to Waterloo, catch the Eurostar to Brussels and journey from there to Aachen in Germany.
Brian Meek of King's College London went to Aachen, where he was so surprised to find that it was the home of "King's College" bar that on his return he published its photo in the college's newsletter, asking for further information. Antithesis phoned the manager of the bar who insisted that there was no reason for the title which is "only a name". Perhaps it is a radical attempt by the college to combat student drinking.
